United States Patent Oiiice 3,052,256 Patented Sept. 4, 1962 3,052,256 REMOVAL F LIQUIDS FROM DRUMS OR OTHER CONTAINERS Victor William Smirles, 14 Kings Road, Cheadle Hulme, England Filed May 7, 1959, Ser. No. 811,676 3 Claims. (Cl. 137-270) This invention relates to improvements in the removal `or withdrawal of liquids from drums or other containers.

Motor fuels and other light hydrocarbons and other liquids are frequently stored in drums or containers from which they are dispersed 'through a tap adjacent the bottom of the drum or container and diculty is experienced in preventing the tap from dripping when not in use.

According to the invention a discharge device comprises a tubular plug provided with a ball valve screwed into the bung of the barrel or container and a delivery tube for screwing into the plug provided with means for lifting the ball oit its seat, the delivery tube during transit being reversed or secured to the filling cap for the drum or container.

The invention will be described with reference to the yaccompanying drawings:

IFIG. 1 is longitudinal section of the device in the closed position.

FIG. 2 is a similar View showing the device in the open position.

HG. 3 is a side elevation device housed for transport.

FIG. 4 is a side elevation to a smaller scale showing the device mounted in a drum.

FIG. 5 is a detail view showing the device housed in the ller cap of a drum.

The discharge device A in the form of a tubular plug is constructed with a body portion having a flanged portion a and screwed at each end a1, one screw engaging a screwed bung b in a barrel or container B when the device is in operation (FIGS. 1 and 2) and the other screw engaging the screwed bung b fwhen the device is housed for transit (FIG. 3).

The body portion is formed with ya shoulder to form a seating a2 for a ball valve C. A spring c is inserted into the body behind the ball C to retain it on its seating, the other end of the spring c bearing on a pin or on a ring c1 screwed into the body portion. The device is screwed into the normal bung b opening in the drum, container or barrel B. During transit a sealing cap a2 may be screwed onto the outer end tube to enclose the ball valve.

4The body portion is recessed at the opposite end to receive a delivery tube or lbi'b D formed with a flange d by which it is secured in position by a flanged nut D1 screwed on to a screwed portion a2 on the body. IThe delivery tube is formed with a delivery aperture d1 from a chamber d2 and with a recess d3 to receive the end of a control rod D2.

The control rod D2 is formed with a shouldered portion d4 to engage one wall of the discharge chamber to prevent its withdrawal therefrom. The inner end of the control rod engages the ball C to lift it ott its seat (FIG. 2).

As an alternative to the housing of the device during transit as shown in FIG. 3 the delivery tube D may be partly in section showing the removed by unscrewing the nut D1 and screwing the tube 65 D into a disc E housed in the lling cap E1.

The discharge tube or bib D may be turned with the aperture d facing upwards when not in use.

To discharge the contents of the barrel or container B, the sealing cap a4 is removed and the delivery tube D is screwed on to the end of the body A in place thereof. The control rod D2 is depressed to lift the ball C oi its seating and liquid is discharged through the apen-ture d1 which may be adjusted to discharge vertically downwards. In order to maintain the ball C off its seat a U-shaped mem-ber Bl may be pivoted on the drum to engage over the end of the control rod D2. A `gauge may be provided in the discharge aperture d1.

Alternatively, the recess d3 in the discharge tube D may be tapered to receive a tapered end d5 on the ycontrol rod D2 and the control rod when depressed will retain the ball C oi its seating. To release the ball C the control rod may be turned in the discharge tube to release the end d5 and the spring c will then close the ball C on to its seating a2; or the control rod D2 may be threaded to screw into the recess d3 or into the wall.

The plug A and bib or discharge tube D may be formed of plastic material such as polyethylene or other material unaffected by the contents of the drum or container or the plug D may be of metal with a lining of polyethylene or other plastic material.

I claim:

1. A discharge device comprising a hollow plug having a body defining a valve chamber containing a spring closed valve and longitudinally spaced similar externally threaded mounting sections, a reduced threaded end section on the plug axially beyond one of said spaced similar threaded sections, releasable means for mounting a `delivery tube having a lateral liquid discharge outlet on said reduced threaded end section, and a control plunger reciprocably mounted in the tube for actuating said valve.

2. The discharge device dened in claim l wherein said tube is ilanged at its inner end to bear against the reduced threaded end section of said plug and a nut mounted on said reduced threaded end section having a ange 101' ysecuring the tube to the plug in a selected position of rotation of the tube to orient the discharge outlet in a desired direction.

3. The device defined in claim 2 wherein said tube and plug have interlitting smooth conical end surface engagement radially inwardly of the tube flange abutment against the plug end.
